A quick question on upgrading ram on my mac box.
Compatibility, speed and ECC...
If I install a slower speed it sometimes does not boot..
Does it need to be in a specific sequence/order in the ram slots..?
Or is it to do with specifically having to be ECC..
What sorts of things would cause my mac to not boot after adding a slot of Ram?
Thanks
